18.4 Bidirectional Pins

PPS selections for peripherals with bidirectional signals on a single pin must be made so that the PPS input and PPS output select the same pin. The I²C Serial Clock (SCL) and Serial Data (SDA) are examples of such pins.

Important: The I²C default pins and a limited number of other alternate pins are I²C and SMBus compatible. SDA and SCL signals can be routed to any pin; however, pins without I²C compatibility will operate at standard TTL/ST logic levels as selected by the port’s INLVL register.
